Devkarin Gambling Spell

Open a booster pack of Magic cards. Cast one
spell from the pack without paying its mana cost
and add the rest to the ante.
Put a trample counter on all creatures with the
word ante in their text box. This counter gives
the creature trample.
"....I love the sound of pack being cracked open,,,is it
just me?...the sound is so soothing!!!!!"
-Marcus Tempus Aurelius
